Zircon U-Pb Geochronology Links the End-Triassic Extinction with the Central Atlantic Magmatic Province
@article{Blackburn2013ZirconUG, title={Zircon U-Pb Geochronology Links the End-Triassic Extinction with the Central Atlantic Magmatic Province}, author={Terrence Blackburn and Paul E. Olsen and Samuel A. Bowring and Noah M. McLean and Dennis V. Kent and John H Puffer and Greg McHone and E.

Life Versus the Volcanoes Correlating a specific triggering event, such as an asteroid impact or massive volcanism, to mass extinction events is clouded by the difficulty in precisely timing their occurrence in the geologic record. Based on rock samples collected in North America and Morocco, Blackburn et al. (p. 941, published online 21 March) acquired accurate ages for events surrounding the mass extinction that occurred ∼201 million years ago, between the Triassic and Jurassic Periods. The…

U-Pb ages show Earth’s youngest flood basalt province erupted in 750 ka starting ~16.65 Ma during Miocene global warming, indicating that the onset of flood volcanism is nearly contemporaneous with that of the MMCO.

U-Pb zircon geochronology is applied to Deccan rocks and it is shown that the main phase of eruptions initiated ~250,000 years before the Cretaceous-Paleogene boundary and that >1.1 million cubic kilometers of basalt erupted in ~750,000 Years.

Hg isotopes display no significant mass independent fractionation within the extinction and depauperate intervals, consistent with a volcanic origin for the Hg, and indicate that significant biotic recovery did not begin until CAMP eruptions ceased.
